Wayland has a mouse capture bug in proton / wine. It particularly seems to be an issue in FPS games. That may contributing to slower adoption for Linux gamers.

KDE Plasma 6 made it to Arch about a week before Tumbleweed. Tumbleweed is also still using Xorg by default for Plasma 6. That said both had it in their repos withing 2 weeks of release. Is there some history here for Gnome on Arch?

At minimum someone has in a traffic fatality.

I just don’t think KDE will be worth it on plasma until KDE 6 / Qt 6. Basic components like SDDM supporting Wayland still have to be solved before KDR provides a first class experience. Try messing around with environments like sway, Hyprland, and Gnome the stability difference is night and day compared to KDE.

There is still way too much instability and too many paper cuts on KDE Wayland. IMO if you have waited this long just wait for their Qt6 release. X11 will remain the best supported experience for KDE 5.
